NCSU Libraries Rapid user testing with prototypesTRLN Annual Meeting ¨C July 2010Susan Teague Rector & Angie Ballard1
What we testedDo users navigate using the expected menu items?Do users pre-select tabs in a tabbed search box before entering search terms?How do users interact with tabbed or non-tabbed search results?2
MethodologyUsers were recruited in situ in the library lobbyNavigation TestingSearch Box TestingUsers were asked to complete 4 of 15 tasks using a working prototype of navigation menus only.Each task required the user to open a navigation menu and indicate which menu item they would select to look for the specified information.Facilitators recorded up to 4 of each user¡¯s menu selections, in order of selection.3Each participant completed 2 tasks using one of the 2 search models; many participants volunteered to answer more than 2 questions.Facilitators documentedtab the participant initially selectedsearch term(s) usedpath taken to complete the task,whether the participant used the  default ¡®All¡¯ tab only, silos only or both. A facilitator assessment of task difficulty was recorded for both tests
Test Setup4Used candy bars as incentives2 laptops with browsers open to prototypeCycled through 15 tasks; 2-4 tasks per user in five minute sessionsD. H. Hill Lobby

Take AwaysRapid testing:Yields more feedback in less time.Best for testing specific features.Tests should last no more than 5 minutes.Saves resources for recruiting, scheduling, logistics, testing, and compensation.Does not save research planning & analysis time.6
Take AwaysInformal test environment may mean more realistic user interactions with product.Results are somewhat skewed toward users who use the physical space.Should be balanced with results from other types of testing.Helps uncover areas for further testing.7
